IMPROVEMENT IN APPLE-PARERS, CORERS, AND SLICERS COMBINED.

Specification forming part of Letters Patent No. 122,553, dated January 9, 1872.

To all whom it may concern:

Be it known that I, GEORGE BERGNER, of Washington, in the county of Franklin and State of Missouri, have made certain new and useful Improvements in Machine for Parin g, Gorin g, and Slicing Apples; and I do hereby declare that the following is a full and true description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of this invention relates to an improved arrangement and construction of a sliding rack-frame, fork-shaft to-impart a part ro tary or swinging motion to knife-stock and, lastly, to certain detail construction of parts, all of which will now more fully appear.

To enable those skilled in these arts to make and use my said improvements, I will now more fully describe the same, referring to-- Figure 1 as a plan view; to Fig. 2 as a part sectional elevation; to Fig. 3 as aface view of slicer and corer, to Fig. 4 as a transverse detail section at line m w,- and Fig. 5 as a detail plan of fork-shaft; Fig. 6 as a plan of paringknife and its attachment and to Figs. 7 and 8 as detail front and side views, respectively, of paring-kniferand its devices.

A is the bed-frame, formed with standards A A to support in their hollow hearings or a the longitudinal fork-shaft B. At one end the shaft B terminates with a fork, 12, while at its opposite end said shaft is provided witha knobcrank 12 for pushing and turning. In connection with fork-shaft B is arranged a slide-frame, consisting of a standard, 0, (through top bearing of which shaft B also passes,) and a sliding-rod, C, (see Fig. 2 at its forward end said rod 0 is formed into a rack-bar, 0, (see Figs. 1 and 2,) and its rod extension is properly guided in its slide movement inthe standards A A The fork-shaft B, playing looselyin its bearings, can readily be slid backward and forward by the operator. In order to revolve the shaft Bthe same is provided with a suitable Worm, D, relatively positioned. In said worm a spring, d, (passing through a slot of bear-in g 00,) engages, the coil of said spring being properly secured to aprojecting pin of the standard A as shown in Figs. 1, 2, 4, 5. When disengaged the spring-Wire d is inserted in a notch, d, of bearing a. The Wire-spring d, made to engage in the worm of shaft B, imparts a back rotary motion to said shaft when the same is opera-ted by its crank. In order that the return and forward sliding motion of fork-shaft B shall be imparted to the rod C with its rack 0 there is arranged Within shaft B a slotted pawl,

E, actuated by a spring, 0, said pawl device being fitted to engage with the collar-bearing of the standard O, as shown in Fig. 2. When, therefore, the operator draws back the forkshaft and adjusts the spring to engage in the worm of said shaft, the same, by its rotary backward motion, withdraws the rack-rod G.

The sliding motions of the rack-rod are made to operate a knife-stock as follows: The knifestock consists of an arm-support, F, its bottom face formed with a pinion, f. At the end of said arm is secured a vertical stock, f, which is inclosed by a hollow stock, G, carrying near its top a swinging arm,g, as clearly shown in Figs. 2 and 7 At the end of swinging arm 9 is secured a projecting pin, g to which, by means of a set'screw, 9 is secured a cutterhead, 9 Further, to the bearings of said out ter-head, is secured a paring-knife, g adjustably by its slot, and a set-screw, 9 in manner indicated in Figs. 6, 7 8. Thus the knife 9*, it will be noticed, can readily be adjusted to out different thicknesses of peelin gs. In order that the paring-knife stock G (which turns loosely on vertical stock f) can be adjusted to suit and bear against the surface of the apple, there is properly arranged on top said knifestock G a coiled spring, H, its Wire end It bearin g against the pin g that supports cutter-head devices. (See Figs. 1, 2, 6, and 7.) The knifestock thus formed is pivoted by its lower arm by proper pin and nut, in relative position to bed A of the machine, so that its pinion f shall gear with rack c of the sliding rod 0, as shown in Figs. 1 and 2. The slide motions of the rackrod thus impart the required revolving motion to the knife-stock proper. Its paring-knife g is made to cut in line with the core of the apple, the spring H pressing hollow stock and devices against the apple. The same is thus properly peeled. A suitable slicer and corer, J, (see Fig. 3,) can be secured in proper position, so that, by the forward thrust of the forkshaft B, after paring has been done, the apple can also be sliced and cored.

The operation of these parts is therefore as follows: The apple to be pared is placed on the fork b of fork-shaft B by its pawl E, is made to engage with sliding standard 0, and the spring 61 is adjusted to engage in the worm D of said fork-shaft. The operator, next turning the shaft B, imparts a rotary return movement to said shaft with apple. Simultaneously the rack-rod O, by its rack c, imparts a swinging turn motion to knife-stock, its knife paring the apple as desired.

To core and slice the apple thus pared the opera-tor disengages the spring d, pushes, by the plam of his hand, the crank-knob b, so that the fork-shaft with apple is passed forward through the slicing-knives and corer. diately as the fork-shaftB is operated backward and forward the forward and reverse motion of the knife-stock occurs. Thus the knife assumes the proper position for operation.

Immeunto set my hand.

GEORGE BERGNER.
